I haven't seen anything that would make Rawr's job easier. They're removing some stats from gear, but they're adding those stats under the hood. If anything, it will make it more difficult. Consider what would happen if they changed Armor
Pen's formula. We can't simply change our ARP gems out and do some parsing, we have to change our Mastery stat, which will affect more stats than just ARP (as an example).

There will certainly be a lot more work needed to model path of the titans and Mastery, too. And adding Reforging to Optimizations...*shudder*

For the casual user, it will make it easier for you to make the "right" gearing choice. But there will still always be that situation where you can't decide if it's better to swap three items out for three other items so you get more Strength
but less Crit.
